Video games have been used in a number of therapeutic applications, such as managing pain in burn victims and helping youngsters deal with depression. A new project in Australia is bringing together video game technology with gesture recognition and some other components to create a virtual reality interactive environment for dementia patients and their caretakers. The project is still in the development stage, and is looking for crowdsourced funds, but the video below shows off the current prototype that will eventually include a 10 m x 10 m projection screen, a touch display, and special lighting.
